Ultrasonic Level Detector, also called ultrasonic level transmitter, or water level indicating transmitter.
ULT-200 ultrasonic level detector, non-contact type level transmitter,
measuring liquid level or solid applications up to 50 ft. / 15 meters,
or flow rates in all types of open channel flow applications.
A transducer is fitted to the top of a silo or tank, facing down towards the material being measured.
Also the flow measurement in open channels and weirs is possible,
as the simultaneous measurement of level and flow in a stormwater overflow basin with only 1 sensor.
Up to 6 relays for tendency alarm, flow pulse output or backwater/sludge alarm, 1 or 2 channel version.

How ultrasonic level detectors work?
Ultrasonic level detectors (ULD’s) work on the principle of measuring the time delay,
between emitted high-frequency sound and its reflection from a surface.
In many applications, these devices have been used successfully as level detectors.
The transmitter’s microprocessor simultaneously fires an electronic pulse,
to the transducer and starts a timer.
The transducer converts this electronic pulse to an acoustic pulse,
which is directed toward the surface of the material being measured.
When the acoustic pulse contacts the surface of the material,
energy is reflected back to the transducer,
which converts this reflected energy back to an electronic pulse.
This pulse is sent back to the microprocessor,
which stops the timer and determines the “time of flight” of the signal.
By combining the speed of sound through air and the “time of flight” of the pulse,
the microprocessor accurately determines the level of the product.
Powerful software removes false echoes from the signal and electronic filters remove ambient noise.
